Weird Apple iOS Bug – Strange Character Autocomplete for letter “I” (uppercase i)

Update: It appears that this is a known issue and is addressed by an update of iOS to version 11.1.1. Though, I do wonder about Apple’s pre-release testing processes.


For whatever reason, whenever I try to type uppercase I (as in “I am going crazy with this”), iOS on my iPhone 7 Plus wants to auto-correct that letter to some very strange character (presumably a malformed unicode character or something similar):

For example, if I go to write an new email and type “i”, I get this bizarre autocomplete suggestion:

If I press space to continue typing (without dismissing the autocomplete), then I see this monstrosity:

I have already gone into Settings > General > Reset and done the “Reset Keyboard Dictionary“, which has not resolved the issue.

iPhone Details:
Model: MNQH2LL
iOS Version: 11.1 (15B93)

Something tells me that it may be related to WhatsApp, since I first noticed the issue there, however I cannot be sure. Regardless, the issue now persists system-wide.
